CZPT Co., Ltd is the expert vacuum pump supplier.

2BV series water ring vacuum pumps are ideal for pumping the gases and steam. Its suction pressure can get to 33mbar (Stomach muscles) (i. e. ninety seven % vacuum degree). If the transformer oil is utilized as the functioning liquid, these pumps are named oil ring vacuum pump and the suction stress can achieve six.7mbar (Stomach muscles) (i. e. ninety nine % vacuum diploma). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps totally. When the liquid ring vacuum pumps operate under the situation near the constrained vacuum for a extended time, it is essential to pair with the cavitation safety pipe in purchase to get rid of the screaming and safeguard the pump.

When the compressor is doing work, the highest strain is .26MPa (Ab muscles). And the larger of discharge force, the more substantial of the electrical power of the compressors. So it is essential that the info of the discharge force is presented to decide on the correct motor.

2BV2-Ex, 2BV6 sequence h2o ring vacuum pumps and compressors are mostly utilized for pumping the explosive gases or function in the flammable and explosive environment. The specialized parameter of every variety is the identical as the corresponding sort of the 2BV2 or 2BV5 sequence products.

2BV series stainless steel pumps can be utilized under the problems with higher specifications for the corrosive-proof or the lustration.

In accordance to the functioning circumstance, the content of all the parts the place the liquid flows (i. e. Pump casing, pump include, port plate, and impeller)are made of various stainless steel as bellow:

SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)

The substance of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti

The mechanical seals are utilized the John CZPT items and the seals materials is optional for FPM or PTFE.

2BV series products have the characteristics as bellow

· The close-coupled design and style is practical to install and can preserve room.

· The CZPT seals are all employed the John CZPT mechanical seals.

· 2BV sequence items have the cavitation protection port. When they perform underneath the situation in close proximity to the constrained vacuum, the cavitation shield port opens (or connects with the separator)to get rid of the screaming to protect the pump.

· Aluminum bronze impeller is of large depth and sporting properly. The erosive-evidence ability of the pump can be improved by employing it. If the parts in which the liquid flows are manufactured of the stainless metal, the pumps can be utilized under the more rigorous situation.

· The distinctive style of the discharge port can shield the pump from the in excess of-pressure to guarantee the best efficient functionality in the operating assortment of the pump.

· The motors are all adopted Y2 collection goods. The defense course is IP54 or IP55 (normal is IP44) and the insulation quality is F.

· The bearings are all utilized the imported goods with manufacturer identify of NTN or NSK.
